Improves horizontal distribution of water in drip
irrigation, resulting in more uniform wetting of
soil

Improves root growth where limitations such as
water logging or compaction is found

Mode of action
• ORO-SOIL improves the infiltration rate of water into
small pores, for example in heavy or compacted soil.
• Orange oil breaks down the greasiness of hydrophobic soils
and also assists with the penetration into smaller pores.

What to expect
Is ORO-SOIL compatible with soilapplied insecticides, nematicides or
liquid fertilizer?
Since the effect of ORO-SOIL lasts
long after application, it is advisable
to apply the product at least 14 days
before the chemical treatment to
prepare the soil by improving the
infiltration and distribution of the
soil-applied chemicals.
ORO-SOIL is compatible with certain
products such as imidacloprid, but
not all soil-applied chemicals have
been tested for compatibility.
Please contact you advisor for the
latest information.

• A single treatment per season improves infiltration rate of
water for subsequent irrigation cycles. In the worst-case
scenario, a follow-up application may be required.
• The product must be properly washed in throughout the
root zone during application.
• Improved infiltration rate in small pores will lead to:
• Less run-off of irrigation water, therefore more effective
use of water
• Improved moisture levels in compacted layers, resulting
in less penetration resistance and better conditions for
roots development
• Improved drainage on soils that are prone to
waterlogging
• Improved oxygen levels in soil
• Increased availability of nutrients

Does ORO-SOIL have any effect on
saline soil?
ORO-SOIL will not neutralize salinity.
Follow the treatment prescribed by
your soil advisor.
Pre-treatment with ORO-SOIL will
improve drainage and may assist
with leaching of salt after chemical
treatment.

How does ORO-SOIL affect microorganisms in soil?
ORO-SOIL is easily bio-degradable,
as tested by an accredited Swiss
laboratory. According to this test,
there was no negative effect on
Rhizobium bacteria.

• Soil condition is more favourable for root growth and
beneficial organisms
• Trials have shown improved root growth and stimulation of
Rhizobium nodules on legume crops as a result of better
aeration and drainage of soil
• Less restriction of root growth in soils where compaction
or water logging is limiting factors. When penetration of
water into compacted layers is improved, the penetration
resistance is reduced making it easier for roots to grow into
these layers.
• In drip irrigation, ORO-SOIL improves horizontal
distribution of water. The result is more uniform soil
moisture distribution and less fluctuation between irrigation
cycles.

The effect on other soil organisms
is currently being tested, however
soil conditions after treatment are
more favourable to development of
beneficial organisms.

Will ORO-SOIL damage plants or
roots?
No root damage has been observed
after ORO-SOIL treatment – even on
seedling roots.
If ORO-SOIL is applied over plant
leaves, the concentration should not
be higher than 0.1%
